Fully complies with AWWA C502 and is available UL 246 and Factory Mutual Approved for allowable configurations.
CONSTRUCTION
51/4” B-84-BAMERICAN-DARLING FIRE HYDRANT
HYDRANT SPRINGAssures quick drain closureand allows throttling.
OPERATING NUTCast one-piece bronze operating nut.Design of the operating thread permitsslow closing of the hydrant valve, reducingthe possibility of water hammer.
O-RINGSSeal lubrication chamber, assure dry-tophydrant, reduce friction, prevent waterfrom reaching the operating mechanism.
HYDRANT RODFurnished in two sections of high-tensilesteel. Upper section has bronze sleevewhere it passes through O-rings. Upperand lower sections are connected by castiron coupling using stainless steel pins.
HYDRANT VALVEConsists of a gray iron valve top and ductilevalve bottom and hydrant valve rubber. Rodthreads are permanently sealed fromcontact with water. Hydrant valve sealsagainst the bronze hydrant seat.
HYDRANT SEATMade of bronze, with accuratelymachined seat for hydrant valvewith two drain ports.
HYDRANT DRAIN RINGSecurely held between barrel and baseflange, provides bronze-to-bronze threadedconnection for hydrant seat. Serves as fournon-corrosive multiport drain channels.
PIPE PLUGProvides access to lubricationchamber. Pipe plug can be replacedwith lubricating fitting to lubricatethe rod threads and thrust washers.
WEATHER COVER(gray iron with rubber weather shield)The word “open” and an arrow showdirection to turn the operating nut. Therubber weather shield prevents water anddebris from entering the housing area.
HOUSING AND HOUSING COVERRetain operating nut and thrustwasher. Rugged constructionwithstands operating forces.
THRUST WASHERTakes upward thrust when opening hydrantvalve and reduces operating torque.
LOWER BARRELThe ductile iron lower barrel provides extrastrength against traffic impact damage.
UPPER BARRELDuctile iron with markings identifyingsize, model, and year of manufacture.
NOZZLESPatented design allows fieldreplacement of damaged nozzlesin minutes by one person.
BASE BOLTS AND NUTSAre stainless steel forcorrosion resistance.
BASESpherical-shaped base has no projections orcavities to obstruct flow or collect sediment.6” base is epoxy-coated ductile iron.
TRAFFIC FEATUREUpper barrel is connected to lower barrelwith breakable traffic flange and 8 boltsand nuts. This feature allows 360°rotation of upper nozzle section.
TOP TRAVEL STOP NUTProvides a positive limit to main rodtravel. Eliminates contact of valvebottom with interior of base, therebyprotecting coating.

Fire hydrants shall meet or exceed
AWWA C502, latest revision. Rated
working pressure shall be 250 p.s.i.g.,
test pressure shall be 500 p.s.i.g., and
hydrants shall include the following
specific design criteria:
The main valve closure shall be of the
compression type. Traffic feature to be
designed for easy 360º rotation of
nozzle section during field installation.
The main valve opening shall not
be less than 5-1/4” and be designed
so that removal of all working parts
can be accomplished without
excavating. The bronze seat shall be
threaded into mating threads of
bronze. The draining system of the
hydrant shall be bronze and positively
activated by the main operating rod.
Hydrant drains shall close completely
after no more than three turns of the
operating nut. There shall be a
minimum of two internal ports and
four drain port outlets to the exterior of
the hydrant. Drain shutoff to be by
direct compression closure.
Hydrant barrels shall be made of
centrifugally cast ductile iron.

American Flow Control’s American-
Darling 5-1/4” B-84-B.
Spring-Loaded Multiport Drains
There are two drain ports and four
drain outlets as a standard feature on the
B-84-B hydrant. The rod spring assures
drains close after approximately three
turns of the operating nut. This important
safety feature prevents wash-outs that
can happen on hydrant designs that do
not have this important feature.
• Positive compression,fast-closing drains
• Travel stop located in top of hydrant • Bronze-to-bronze seating
• Short, lightweight,disassembly wrench
• Easy 360° rotation of nozzle section• All bases are epoxy-coated ductile iron
• Centrifugally cast, high-strength ductile iron lower and upper barrel
• Sealed lubrication chamber• Lower valve ball is epoxy coated
The B-84-B hydrant has these standard features:
American Flow Control’s American-
Darling 5-1/4” B-84-B hydrant incorporates
more than 80 years of experience in
design, manufacture, and field
experience. This means dependable and
efficient operation when needed.
Introduced in 1984, the B-84-B
hydrant is rated at 250 p.s.i.g. and is
seat tested at 500 p.s.i.g. This hydrant
meets or exceeds all requirements of
AWWA C502 for dry-barrel hydrants.
The B-84-B hydrant is loaded with the
features you expect from a high-quality fire
hydrant. The all bronze seat and drain ring
ensure that the B-84-B hydrant is easily
repaired by just one person.
Optional UL-FM
The B-84-B hydrant is listed by
Underwriters Laboratories, Inc., as
meeting their standard UL 246, latest
edition. The Factory Mutual Research
Corporation has approved the B-84-B.
Both Underwriters Laboratories and
Factory Mutual Research Corporation
require that we consistently manufacture
and test our hydrants in full compliance
with their stringent requirements. Our
facilities are subject to periodic
inspections to ensure we are in
compliance with their standards.
BENEFITS
SPECIFICATIONS
FEATURES
Sealed Lubrication Chamber
Seals operating threads from water
and debris which greatly reduces
routine maintenance.
Top Travel Stop Nut
Helps prevent stem buckling and
damage to bronze components which
may occur if excessive torque is applied
in the full open position.
